The update introduces Lollipop to the OnePlus One, along with OnePlus’ take on an Android skin, which like other OEMs are calling an “operating system.” There isn’t much of a feature list to report back on at the moment, but OnePlus has said that there are gestures built-in to areas like the lock screen, customizable quick settings toggles, and a file manager. While that list may not seem like much, Lollipop is really all you should care about, OnePlus One owners.

That’s the good news. The bad/time-consuming news is that you have to manually flash OxygenOS – this isn’t an over-the-air (OTA) update.

So what does that mean? Well, they have a set of detailed instructions over at their forums that we have linked below, but the basics are this. You need to download the OxygenOS update file which is roughly 700MB. After that, you need to have adb and fastboot setup, know how to flash TWRP custom recovery, and finally, be prepared to fully wipe your phone. If that all sounds like the good ol’ days of flashing a ROM, that’s because that’s exactly what we are looking at here.

The instructions aren’t really all that bad, but if you aren’t familiar with adb or custom recoveries, this could all sound like we’re speaking a different language. If you have even a basic familiarity with what I’ve just said, you should be able to get OxygenOS up and running in no time.
